CA 2564716
The present invention provides an abrasion resistant composition comprising fluoropolymer and an effective amount of micropulp to increase the abrasion resistance of an article such as a film formed from the composition by at least 25% as compared to film formed from the fluoropolymer by itself. In an especially preferred embodiment, the composition also contains an effective amount of pigment to further increase the abrasion resistance of film formed from the composition as compared to film formed from the fluoropolymer by itself. The invention is especially useful for films formed on a fuser roll.
Cette invention fournit une composition résistante à l~abrasion, contenant une fluoropolymère ainsi qu~un nombre de micro-pulpes suffisant pour augmenter la résistance à l~abrasion d~articles tels qu~une pellicule formée d~au moins 25 % de cette composition, en comparaison d~une pellicule formée de la seule fluoropolymère. Sous une de ses meilleures formes, cette composition contient également un nombre de pigments suffisant pour augmenter la résistance à l~abrasion de la pellicule formée de cette composition, en comparaison avec la pellicule formée de la seule fluoropolymère. Cette invention est spécialement utile pour les pellicules formées à l~aide d~un rouleau d~unité de fusion.
